The number of terminal oxygen atoms present in the product B obtained from the following reaction is _____________.

FeCr₂O₄ + Na₂CO₃ + O₂ $\to$ A + Fe₂O₃ + CO₂

A + H⁺ $\to$ B + H₂O + Na⁺

Accepted Answer

\mathrm{FeCr}_{2} \mathrm{O}_{4}+\mathrm{Na}_{2} \mathrm{CO}_{3}+\mathrm{O}_{2} \longrightarrow \mathrm{Fe}_{2} \mathrm{O}_{3}+\mathrm{CO}_{2}

+\mathrm{Na}_{2} \mathrm{CrO}_{4}

(A)

{Na}_{2} {CrO}_{4} + H^{+} ⟶ {Cr}_{2} O_{7}^{- 2} + H_{2} O + \overset{+}{Na}
